Triple Head Monitor

Hi guys

At the moment I have dual monitor setup, but I want to buy another 22" LCD and have triple screens. Just need more desktop space. So how can I do this. I have a dell 8400 and I dont know if I can fit another graphics card in, I am currently using a VGA-DVI convertor for my second monitor which is on my Geforce 7300 GT card.

So bassicly my question is ? what is the best way to go about this ?

sorry if this is a bit vague!


cheers

Would the Matrox solution work?

I have seen that one
but will it work for linux ?
